Crossed and inverted words (C++ programming)

I need a program that when a word is entered knows if the word is odd or even of characters and if it is odd it should display the word in a cross and if it’s even it should display the word inverted.

Example:  Microsoft

   M        M
    i      i
     c    c
      r  r
       o
      s  s
    o     o
   f       f
  t         t

Example: UNIX

  U X
  N I
  I N
  X U
